This ctg. deserves a thread. I know it's been mentioned in several other threads, but not it's own thread - at least I don't think so.

Guys - anyone looking for a light recoiling round that will do it all in NA and most in Africa need look no further.

These rifles are available in the States from Allen's Armory, and in Canada from Tradeexcanada, both . com. As well, both places sell M46's and M146's in not only 9.3x57 but also in 9.3x62.

For handloaded ballistics, one can safely use maximim .358 Winchester data with the same weight bullets & go from there. Anyone with a lot of handloading experience can then load for heavier bullets, the 270 Speer or 286gr. Hornady or Norma bullets. PriviPartisan bullets seem to be specifically designed for this round and work extremely well in it, as-does the 270 Speer.

Handloaded in a M46, which is virtually a Sedish 96 action, can achieve 2,200fps with 286gr., 2,300fps with 270's and 2,350 to 2,375fps with 250's, 2,450fps with 232's and 2,550fps with 225gr.(re-sized .375's).

Handloaded in a M146, the Model 98 action, the 9.3x57 can duplicate the 1925 9.3x62 data, which is still being loaded today, a 286gr. running around 2,340fps.

There are no flies on this ctg. just as the 9MMMauser has a following, the following today behind these Swedish Mausers in 9.3x57 is much larger. Literally hundreds of them have been sold in the past couple years - maybe thousands - just from Tradeexcanada alone.

The best powders seem to be the same as in the 9.3x62 - H4895, BLC2, and H335 in my experience, while others are playing with WW748, IMR4320 and IMR4064.

It is best to measure the chamber in some manner before firing the rifle. This round escaped the CIP and SAAMI regulation for some reason, so while there are 'general' standards adhered to, they can run large in grove diameter and chamber length to the shoulder. My own Husky M46, made in 1929, sports a chamber that is .019" longer than the factory 57MM shoulder datum line, as well, it has a tight neck, but also has a .370" groove diameter.

For me this is a hunting rifle and my favourite. I dare say, I enjoy shooting this rifle a lot more than the 9.3x62 or the .375/06IMP.
.365" (Privi's) and .366", Norma and Spear bullets all shoot 1 1/8" or less at 100 meters. That includes re-sized 225gr. Hornady SP's as well as re-sized .375 300gr. RN's.

I am pushing the RN's at 2,175fps & the same load with 285g.r Privi's runs 2,200fps.

The Model 98 action of the M146 Hudky, adds another 100fps to these stats, easily.

My web expansion is only .0005" over new, sized brass, with less than a thou neck expansion. I can only use bullets to .367" diameter as larger won't allow sufficient neck expansion.

I expand 8x57 Mauser RP brass straight in one step, then size the brass in Hornady dies to a crush fit on the shoulder. Brass will never need trimming, as the chamber neck is a bit long as well. This does not effect it's shooting capability.
